The standard deviation of the mileage for the sample of convertibles is 1.98977 miles.
<h3>What is standard deviation? </h3>
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.
<h3>What is the standard deviation of the mileage? </h3>
In order to determine the standard deviation, take the following steps:
- Determine the mean of the observation:
(25 + 25 + 24 + 21 + 21 + 21 + 20) / 7 =22.43
- Determine the difference between each value and the mean and then square the result:
(25 - 22.43)² = 6.6049
(25 - 22.43)² = 6.6049
(24 - 22.43)² = 2.4649
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(20 - 22.43)² = 5.9049
Sum of squared difference = 27.7143
- Determine the mean of the square differences and then find the square root of the mean:
√27.7143 / 7 = 1.98977

Answer:
y = 1
Step-by-step explanation:
To find the Horizontal Asymptote, you have to look at the degree of the numerator and denominator.
- If n < m, then y = 0
- If n = m, y = coefficient of
divided by the coefficient of 
- If n > m, then there is no Horizontal Asymptote
Answer:
2010.62
Step-by-step explanation:
the formula to find a cylinders volume is r and h so you just divide 14 and get 8, then you get the 10 and you solve for how you would usually get your cylinder volume. which is V=πr2h=π·82·10≈2010.62
